Light Years are a measure of:

• time
• speed
• distance
• light

A light year is...

• The speed light travels
• How long it takes light to get to you from the sun
• The distance light can travel in a year
• How many years it takes light to be emitted

Why is it considered inappropriate to use light years to measure distances within our solar system?

• The light year is too big

• The solar system is to small

• light doesn't travel in our solar system

• We only use light years to measure sizes, not distances

It takes 8.9 years for light produced on Carinae V602 to reach the sun.  If Star X is 30 times as far from the sun as Carinae V602 is, how far is Star X from the sun, to the nearest light year?
